After two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represent her salary after x years on the job. assuming that the change in her salary over time can be approximated by a straight line, give an equation for this line in the form y=mx+b

y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600
